Rough Idle

My Car has developed over this Past week a Rough Idle . It even Stalled on me when I put it in Reverse to back into a Parking Space . I know there could be Numerous Reasons for this Condition , but I was Hoping to Isolate it down a Bit . Maybe Fouled Plugs ? Distributor Parts ? Injectors are CLEAN , no Prob there . Idle Air Control Valve developed a Different Voltage due to >? Just Needs a Full Tune Up ?
The Car Runs Great , but when I am Idling at a Stop sign , my Tach is a Little to Jumpy for my Tastes . It usually was Right on 500RPM's awhile ago . I am use to a Rock Hard Idle on most my Cars , but this one just dosen't FEEL RIGHT Lately . Any Suggestions to how I might Solve this Problem ? Any input would be Welcome . Thanks ..........MARK



I do have Flow Tech Headers on this Car , and my OX Sensor works OK BTW .

Check your plug wires. Especially the coil to distributer wire. Other than that, start taking voltage drops from the distributer and verify coil resistance.

Thanks for the Response Dirtbik3r . I went out and removed each Spark Plug Wire and noticed a little Corrosion on 4 of the wires at the Distibutor Terminals . I live near the Ocean and Salt Air Corrosion has always been a Problem for my other Cars . I Cleaned the Contacts , and Put the Wires back on . When I started the Car and it warmed Up , my Tach needle was Right on 500 Rpms in Drive . No Stumbling or Erratic Tach Movement in Idle . Thanks for your Advice Bro . An Easy Fix that did not cost me Money . I Owe you a BRAU for that one Dude ! LOL


By the Way , here is a Pic. of my Old Porsche Unleashed Online Racing Team Roster the [XR] 's . I hope to Own a Porsche one day before I die . To me , the Best Car Ever made .


Signed........[XR]Herr
